The bones of the joint articulate with each other within the joint cavity. They are highly moveable and all have a synovial capsule collagenous structure surrounding the entire joint a synovial membrane the inner layer of the capsule which secretes synovial fluid a lubricating liquid and cartilage known as hyaline cartilage which pads the ends of the articulating bones.
Bursas are found between structures that glide upon each other and all motion at diarthroses entails some gliding the amount varying from one joint to another.
